Up until just a day or so ago - everything was fine with the independant details and importing them (the whole drawing) into Plotmaker.  Just the other day though - plotmaker gave me a message that one of my details (that I had edited) was empty upon import.  I check in Archicad (9) and its there in both the project map and then view set.  Try importing again with same results.
So today I created a new independant detail with simple lines and dimensioned it.  When I imported into plotmaker, the dimensions show up but the lines dissapear.  I have done everything I can think of to see if I can figure it out but alas - nothing.
Each time I create a new independant detail in the project map, (its cloned in the view sets) and draw lines, it draws in fine.  I then close the detail - or save and close or save the project with the detail open or adjust layers, layer settings, and display settings, or ... or... etc. etc .etc.....  But if I try and import it into plotmaker - the lines are gone.
Moreover - if I close that file and reopen it - the independant detail is there in the project map and the view sets, but the lines are gone.
Any ideas what is going on with this?  I'm floored.
